Come the end of the week, most of us are beginning to run out of puff.

Hauling yourself out of bed on a Friday to drag yourself into work is a tough ask. By lunchtime, the eyelids are heavy, enthusiasm is at a low and the thought of a nap on your desk is very tempting.

Perhaps, then, you can see much of yourself in this weary gelada baboon letting go with an enormous yawn before settling down for a nap on her favourite rock. All that monkeying around at New York’s Bronx Zoo had clearly taken it out of Suriya as photographer Alan Shapiro, 50, stopped by her enclosure.

He said: ‘They are such amazing-looking creatures. I can watch them for hours. They are so similar to humans – they move around and act just like us. Gelada baboons usually show their teeth as a sign of aggression, to say “stay away”. But in this case, she was just tired. She was settling down to have a nap.’

Gelada baboons are found in the Ethiopian highlands. There are estimated to be 200,000 in the wild. They can live for 19 years and are the only grazing primate in the world.
